mine only comes to 297W, at 80% useage. Not bad for 2 cd drives, 2 HDs, and an X800GTO PCI-E, and a 3200 Winchester
477W for me. My 480W seems right on the money then. ;)
Sli = big power bills ;P
Nice calculator.
LOL, my Gaming rig/Semi-server = 345W at max overclock:
A64 3000+ 2.75 Ghz 1.475V
4x1GB (used to be, now 2x1G)
6600GT
1xIDE, 4xSATA
My Server rig = 267W at minimal voltage
A64 3000+ 1.8Ghz 0.975V
4x512M
6200TC
3xIDE 4xSATA
But, I gave them a 550W and 580W PSU!!
I have a 420W PSU, and its more than enough for my system at the silliest of overclocks, and note I have a prescott P4, it uses 160 Watts at its highest overclock. Most people buy PSU's that would power 2 computers at a time.. its just silly really.
The only thing is, I used to move a lot less stuff with a 370W PSU (Not no-name brand but I wouldn't say it is too high up the list) and I lost one HDD every month until I realize the PSU was crap. Even if it say it only require 267W and my old 370W couldn't push it properly!!
Depends on the manufacturer, Tagens are rock solid.. a PC World 'White box' for example would be complete pants..
It pays to dish out for quality, rather than quantity.
I hope that wrong ;)
Says my current system is 473w (current PSU 400W and everything is rock stable) and when I place my 2nd 7800GT in tomorrow it will jump to 563W!!!
374w at 100%, not bad actually was expecting more
243W... not surprising considering the sorts of components I have (e.g. Mobile Barton, 6600GT, not much else!)
389W, and giving it 650W lol, a bit overkill this time :D
Quality is all that's important. Often a quality PSU will be a branded one with x00 Watts, but you are paying for the quality, not the extra wattage. PSU power has been done to death on here, but basically noone needs more than about 300W. Hexus has an article which shows the same thing.
And yet everyone still piles in with the 'I paid for 1000W so my ***** must be bigger.'
The problem with cheap power supplies is that they give the power to the wrong rails. You really need it on the 12v rails while they have pumped up 3v and 5v rails which do bugger all these days.
actually the main problem with cheap power supplies is they use cheap AC/DC converters and waste a whole bunch of power in that process alone, the other problem is with these cheap converters is that the power can fluxuate wildly..
so Whitebox 700Watt PSU is more like 350Watts. Looking for efficency in with the specs is something you want, 90%+ efficency is good, the weight of the PSU is a pretty good indicator of this.
Useful but it isn't accurate and its a bit misleading because they dont explain that it isn't total PSU wattage isn't whats important - its amps per rail, particularly the +12v rail that likely to be critical factor.
Still, anything to sell you a overpriced PSU that you don't need.
